MSE was absorbed into Windows Defender in Windows 8 & 10. I don't recall any publicity from Microsoft telling their users this - I only know because I did google searches on how to install MSE on Win8 which turned up the answer that its already in there, just renamed. In my experience, a lot of people, including IT people who should know, have not gotten the message. There are a lot of people paying a lot of money for crap snake oil when they could have free (arguably better) snake oil.

Windows Defender in Windows 8 resembles Microsoft Security Essentials and uses the same virus definitions.
